SPECIFICATION forming part of Letters'ratent No. 549,226, dated November 5, 1895.

Application filed December'l, 1894. Serial No. 530,522. (No model.)

To all whom it may concern: Be it known that I, THOMAS H. BRUNER, a

'citizen of the United States, residing at Temple, in the county of Bell and State of Texas, have invented certain new and useful Improvements in the Mode of and Means for Baling Fibrous Materials; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to the art of baling fibrous materials, and more particularly such iibrous materials as can be formed into a lap or web.

My invention has for its object an improved method of forming the bale, as well as improvements in that class of compresses or baling-presses adapted to form a cylindrical bale. It has been customary to form the bale by winding a web of ber upon a cylindrical core, and in order that the latter may withstand the pressure of the compressing-roller a solid core of suciently strong material had to be used to prevent such core being crushed; but in view of the space taken up by the said solid core, and also in view of the weight thereof, a tubular core of metal of comparatively small diameter has been substituted. The use of such a core-roll is not only more expensive than a core of sufficient diameter made of wood, but it is also considerably heavier, entailing an increase in cost of transportation. It is the design of my invention to obviate this disadvantage by the use of a solid or tubular core of wood of small diameter, and to avoid the crushing of the same under the Weight or pressure of the compressing-roll I provide means for `supporting the compressing-roll from the base or lower roll in starting the formation of thebale-that is to say, when the core-roll is empty, and preferably until said core-roll has received one or more windings of the iibrousmaterial, so as to form a cushion thereon that will `prevent the crushing of the core-roll.

In compresses or baling-presses as heretofore constructed for forming a cylindrical bale by winding a bat or web of fibrous material upon a core-roll a bale having square ends cannot readily be obtained owing to the irregular winding of the bat or Web, so that said ends' are not only more or less conical, but also more or less ragged or loose, thereby rendering it more liable to destruction or damage by fire, and entailing a proportionate increase in the cost of insurance, while in storing or transportation of such bales a considerable amount of space is lost. It is the further design of my invention to provide means whereby a bale having square and smooth or even ends is obtained, and whereby end coverings or caps or heads for the bale are provided at the same time, and whereby said caps or heads may be applied an'd secured in position before the bale leaves the compress; but that my invention may be fully understood I will describe the same in detail, reference being' had to the accompanying drawings, wherein- Figure 1 is a front elevation, partly in section, of so much of a baling-press for forming cylindrical bales as is necessary to illustrate my invention. Fig. 2 is a similar view illustrating a modification in the devices for supporting the pressure-roll from the base or lower roll in starting the formation of a bale. Fig. 3 is a vertical section thereof. Figs. 4 and 5 are perspective views illustrating the completed bale. Y Fig. 6 is a cross-section of a bale without the covering, and Figs. 7 and 8 are detail views.

In Figs. 1 and 2 I have illustrated my invention in its application to the Bessonette compress or baling-press shown and described in reissued Letters Patent, dated January 19, 1894, No. 11,422, and the parts shown in said iigures bear the same reference-numerals as the corresponding parts shown in the drawings forming a part of the aforesaid reissued Letters Patent, though I would have it understood that my invention is` applicable to any type of compress or baling-press inwhich the compression of the fibrous material is effected between rolling surfaces, one or both of which are adapted to yieldin kaccordance with the increase in the diameter of the intermediate body of iibrous material.

Referring to Fig. 1, 2 indicates the side standards 14, the base or bed roll, revoluble IOO in fixed bearings 6in said standards. 25 indicates the upper roll, revoluble in bearings in ianged boxes 23, adapted to slide in vertical slots 7 in the aforesaid standards 2, and C indicates a core-roll of wood. The core-roll may be a solid one, though I prefer a tubular core-roll with a view to decreasing the Weight thereof, said roll having the opposite ends of its core coned or flaring outwardly for the reception of the cone ends of center ing-spindles 17, adapted to revolve in bearings in boxes 1G, adapted to slide in vertical slots 7 in standards 2, one of said spindles being screw threaded and working in a threaded bearing in box 16 for the purpose of securing or centering the coreroll or releasing the same when the bale is completed, said threaded spindle having its end squared for the reception of a crank.

Upon each journal 13 of roll 1i is secured a small wheel WV, similar wheels XV being secured to the journals of roll 25, while the core-spindles 17 carry wheels W72 of such diameter that when an empty core-roll C is positioned between rolls 14 and 25 for forming a bale said rolls or the upper roll 25 only will be held out of contact with the core-roll until a certain length of the bat or web of ber is wound on said roll to form a cushion thereon. In this manner the upper roll 25 is supported from the lower roll la at the beginning of the formation of a bale, the pressure upon the fibrous `material increasing in proportion to the increase in the diameter of the bale until the full pressure of the roll 25 is exerted upon the fibrous material, which pressure continues during the formation of the bale and until itv is completed, or until the bale is of the desired diameter. On the opposite ends of the shaft, or on the journals of roll 14, which project from standards 2, are secureda gear-wheel 53 and a bevel-pinion 15, and on the journals 24c of roll 25 are secured a bevel-pinion 26 and grooved pulley or sheave 27 for purposes fully described in the aforesaid reissued Letters Patent.

In order that a cylindrical bale having square ends may be obtained, I mount upon the opposite ends of the core-roll C a circular abutment, which may be a disk of wood or of sheet metal Il, that confines the fibrous` material as it is wound and compressed on the core-roll, said disks constituting the end coverings or heads for the completed baleand being of substantially the same diameter as the latter.

The formation of the bale will be readily understood from the above description, and after its completion and before its removal from the press I cover the body thereof by winding thereon a covering of the usual material, the edges of which are secured by means of aband ortie "of sheet metal, tacked to the periphery of the heads H, and said covering c may be 'further secured by one or more ties t, encompassing the `body ofthe bale and secured in any usual or desired manner. (See Fig. 4.) The ties on the body of the bale may, however, be dispensed with by using a narrow strip of covering material c' and winding the same spirally on the bale from head to head in such manner that the successive convolutions will overlap each other and securing the ends of the strip of covering material to or through the medium of the heads H, as shown in Fig. 5.

When the heads I-I are made of sheet metal, I make the same of such a diameter relatively to the bale proper as to admit of bending the edge over or onto the covered bale, forming an overlapping iange 7L, and to facilitate this the said edge is slitted radially in a well-known manner, and as the bale is slowly revolved in the press the tongues are bent over by hand and are then iirmly pressed onto the bale bythe action of the rolls 14 and 25, a wire or tie t2 being at the same time ap plied to finally encompass the flange 71j thus formed, and thereby secure both the heads and covering to the bale, and in order to better protect the baled material against fire the body of the bale may be covered with sheet metal.

In order to prevent the bulging out of the sheet-metal heads Il from any cause, instead of forming therein a hole for the reception of the core-roll the central portion of the head can be slitted radially from its center for a sufficient distance to form tongues h', adapted to be turned into the bore of the core C, as shown at the left in Fig. 7, or onto the core, as shown at the right in said figure, when said head is applied to such core, and several of the said tongues may be secured by tacks, i

or when the tongues are turned into the core a plug p may be driven into said core, as shown in Fig. S. It will, however, be understood that I do not limit myself to any particular mode of or means for securing the heads to the core or the cover to the bale, as these may be varied in many ways without departing from the spirit of my invention; nor do I desire to limit myself to the described means for supporting the compressing-roll from the bed' or base roll in starting the formation of a bale or when the core-roll is empty, as these may also be varied, for instance, as shown in Fig. 2, in which the wheels W, W, and V72 are dispensed with. The core-roll in this case is made slightly shorter than the bed and compressing rolls, and I use a spindle or mandrel M, that fits the bore of said core, and apply to each end of the mandrel a eol lar or sleeve S, whose inner portion has bearing upon roll 14 and supports the ends of roll 25, thereby also supporting the latter roll from the bed or base roll, and in this arrangement the heads Il are also supported from the collars or sleeves S.

In the construction shown in Fig. 1 the end- Wise movement of the head Il is prevented by the wheels YV2 on cone-pins 17, while in the IOO IIO

arrangement shown in Fig. 4 this endwise movement of the heads is prevented by disks D on the journals 13 and 24 of the bed-roll 14 and compressing-roll 25, respectively, said disks being adjustably secured t0 said journals by means of set-screws s, so that a head of wood or sheet metal can be applied to the sleeves and the space between said disks and the end of the rolls 14 and 25 adjusted accordingly, the sleeves and the mandrel M being removed after the bale is completed.

Of course in the construction shown in Fig. 2 the cone -pins 17 take in cone bearings formed in the ends of the spindle or mandrel M.

In order that the bat or web may be more readily unwound from the core for the purpose of Working up the fibrous material, I interpose a wire, cord, or tape between the convolutions of the web of fibrous material, by means of which the bale can be revolved, said wire or the like being used more for the purpose of sustaining the draft necessary to revolve the bale in unwinding, though it also assists in separating the convolutions 'of the web in unwinding, and this may be rendered more effective by winding a wire or the like at different points of the length of the bale. This wire, cord, or tape is wound upon the core with the material, as shown in Figs. 3 and 6, and to avoid as much as possible an increase in the diameter of the bale at the point or points where said wire or the like is wound in the wire is or may be suitably guided to and fro for a certain distance or wound upon a spool s from end to end in opposite directions, so as to give the wire atraversin g motion equal to the length of the spool. The end of the web w, with wire w on top thereof, havingbeen inserted between the 'core and bed roll 14 and the latter and the compressing-roll 25 set in motion, said wire will be wound with the web onto said roll, as will be readily understood and as clearly shown in said Fig. 3.

,Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a baling press of the class described, the combination with the base roll and a co- 5o operating pressure roll adapted to move toward and from said base roll, of bearings for a core roll supported from said base roll, substantially as and for the purpose set forth.

2. The mode of forming cylindrical bales of 5 5 fibrous materials having fiattened ends, which consists in the following consecutive steps, to wit: winding the material onto a core be tween circular confining abutments, subjecting the material to pressure during the winding, and connecting the conning abutments with the completed bale before releasing the same from pressure, for the purpose set forth.

3. The mode of forming cylindrical bales of fibrous materials with flattened ends, which consists in the following consecutive steps, to Wit: winding the said material onto a core between circular confining abutments, subjecting the material to pressure during the winding, winding a sheet of covering material around the bale, and securing such covering to or through the medium of said confining abutments before releasing the bale from pressure, for the purpose set forth.

4. The mode of forming cylindrical bales of fibrous material having protected ends, which consists in winding the said material in the form of a bat or web onto a core between circular confining abutments, subjecting the 8o material to pressure during the winding, covering the bale by spirally wrapping around the same a strip of suitable fabric While said bale is being revolved and under pressure, and securing the ends of the covering to, or through the medium of the confining abutment-s, for the purpose set forth.
